Come in and sit down , Jack . Now , what's the trouble ?   I've got a terrible pain in my stomach , Doctor .   I see . When did it start ?   It started yesterday . I didn't eat any supper .   Have you got a temperature ?   I think so . I feel very hot .   Let's see . Yes . You ' Ve got quite a high temperature .   I've got an awful headache , too , and my throat hurts .   Hm .. I think you ' Ve got the flu .   Is it serious ?   No , not at all , but you must stay in bed for three days and take this medicine .   How often must I take it ?   Three times a day after meals .   Thank you , Doctor . Goodbye .
